PG-FP5

Renesas Flash Programmer

Answer:

After the flash programmer has erased the flash memory, the boot area differs according to the specification of [Operation Mode] when the flash memory was erased.

When the specification for [Operation Mode] is [Chip]:
Since the boot flag is initialized by erasing the flash memory, the boot area after a reset will be boot cluster 0.

When the specification for [Operation Mode] is other than [Chip]:
After the flash memory is erased, since the value of the boot flag before erasure is retained, the boot area after a reset will be the same as the boot cluster before erasure.
